Abstract

1286235 Mounting rotors on shafts ROLLS ROYCE Ltd 20 Jan 1970 2744/70 Heading F2U [Also in Division F1] A rotary bladed structure for a fluid flow machine comprises adjacent coaxial bladed rotors arranged for rotation together, the bladed rotors being connected together by a helical torque-transmitting connection which permits limited axial and angular relative movement of the rotors, there being loading means for loading the connection against the relative movement. In the embodiment the rotor is the HP compressor rotor of a gas turbine engine, the rotor comprising bladed rotor discs 22, 24, 26, 28, 30, the discs 22, 24 being formed of different material to that of discs 26, 28, 30, the discs 22, 24 being welded together at 25 and the discs 26, 28, 30 being welded together at 31. The adjacent discs 24, 26 are formed with axially-extending flanges 44, 46 which are formed with helical spline teeth 48 which teeth interengage to form a helical spline connection. The compressor rotor comprises also a shaft portion 50 which is connected to a shaft 51 of the compressor drive turbine by a bolted flange connection 52, 53, 58. At the forward end a shaft 59 is connected to the rotor disc 24 by a straight spline connection 66, 68, the shaft being supported in a bearing 60. The helical spline connection 48 is pre-loaded upon assembly by means of a torque tube 54 provided with flanges 56, 60<SP>1</SP>, the flange 56 being secured between the shaft flanges 52, 53 by the bolts 58 and the flange 60<SP>1</SP> being secured to the flange 62 of the shaft 59 by bolts 64.
